Appiieaiion inea .Tuiy ze,

My invention relates to the art of illumination. and particularly todevices adapted to receive and position light sources and s urround themwith reflecting and diffusing means to cause the light rays to bedelivered in a ceitain definite manner.

My object is to construct a fixture carrying two light sources, surounded by diffusing means combined with reflecting means, .to directthe rays from the light sources in dif- Y ferent directions and yetcause the two light sources to function together for producing thegeneral effect desired in the illumination.

Mv inventionV consists of certain detailed construction hereinafter setforth, pointed out in iny claim, andvillustrated in the yaccompanyingdrawings, iii whicli- Fig. 1 shows a side elevation view vof my fixture,part of the globe being broken away to reveal the inner' construction;and

Fig. 2l shows, in reduced scale, a section taken on line 2-2 of Fig. 1.

Similar reference numerals refer to similar parts throughout the entiredescription.

Referring to the accompanying drawings, I employ a globe holderlfhattached, in the ordinary manner, to a chain Ahanger 11, or .acanopy. In the canopy is mounted an electric light socket 12, suppliedwith proper currentcarrying wires (not shown) The upper portion 13 oftheglobe, preferably constructed of diffusion glass, is secured to theglobe holder in the usual manner. A metal ring lll is Y secured bystraps 15 to a hiclrey 15 in the canopy 10, as shown. rlhis metal ring14: en gages the lower edge of the globe portion l-3, and is providedwith a cii'cuiiifereiitial flange 17, within which the lip of the lowerportion 21 of the globe rests. A inet-'al strap 1SY eX- tends across theringl 111, and is orificed to sup-- port a socket 19 which dependstherefrom.

Supply wires 2O conduct current to this vsoclret 19, the said wires 2Oobviously passing upwardly and through the hickey 16. ylhe lower portion21 of my globe, also preferably formed of diffusion glass, is held inposition by the flange 17 iii any ordinary manner, such as isillustrated at 22, and shown iii detail in Fig. 1. Electric light bulbs23 anc 24s are mounted in the sockets 12 and 19 respectively. Aconcavo-convei; reflector 'is secured to the metal ring let andcentrallypositioned with relation to the light sources 23 and 24. Theupper face of the reflector 25 will receive 1%27.

rays from the light source 23and direct them insetti;

upwardly, and the lower face of said reflector will receive rays fromthe light source 211 and direct them downwardly and outwardly. It

is very important that the light sources 23 and y 24 be in propervertical alignment, so that the cominoii reflector 25 may function torovide an even and regular from each source. Y

in constructing lighting fixtures, the prob leiii 'of the illuminationengineer is to utilize the light so that theinost effective distributionfor the purpose in mind may be produced. ily fixture is designed to givea more or less coiicciniate'd delivery of diffused light upon` theworking plane from the lower light source, and a full distribution oflight over the ceiling' and in the corners of the room` from the upperlight source. By properly aligning my two light sources, and using adivided globe with a concavo-convex reflector distribution of tie raysmounted between the globe portions to direct .f

'the light, I obtain, Vfrom Atwo independent light sources designed tofunction together for general room illumination, a inostisatisfactorydistribution of light. ,Y

lnniy drawings Iliave illustrated a preferred construction, but itisobvious this is only one illustrationof how iiiyinventioii may beadapted for use, and l do not want to beliinited in the scope of myprotect-ion, eX-r cept as set forth in the appended claim.

Having described iiiy invention, what I Y and desire to secure by Uniteds jard as new, Stateslietters i)ateiit, is: y i

in a lighting fixture, the combination, with a canopy, of en electriclamp' socket depending therefron'i, an electric lamp mounted therein, adifl'usiiigglass shade detachably se'- cui'cd to said canopy andenclosing said lamp,

a reflector closing the bottom of said shade,

all of the rays from said lamp not passing directly through said shadebeing redirected by said reflector, whereby the ceiling and uppercorners of the rooin are illuminated,l

there being a central opening in said reflector,

'an `electric lainp socket depending therefrom,
